Is there such a thing as that concept? Yes.

Has someone implemented this? Depends on how you define "chaining".

If you mean you use one credential to get another credential:

Digital Bazaar has (in a proof of concept capacity) demonstrated the
consumption of a digital identification credential issued by a government to
receive a TruAge age verification credential.

If you mean, you embed one credential inside another credential:

I believe some of the VC EDU folks are exploring that use case... and yes, if
you use VCs that are protected by Data Integrity (was Linked Data Signatures),
then you can do arbitrary nesting of digitally signed VCs.
